摘要
准噶尔盆地腹部自晚古生代至第四纪经历了台地型海相盆地、前陆型海相盆地、裂陷型残留海盆地、坳陷型陆相盆地、振荡型陆相盆地和收缩型陆相盆地等6个构造、沉积演化阶段;鞋陷和坳陷阶段为烃源岩的主要发育时期。本文探讨了烃源岩层的空间分布及热演化史,阐述了盆地腹部的枸造及沉积特征,指明存在3个有利含油气领域。
From Paleozoic to Quaternary, Junggar Basin Went through six periods of evolution of structures and depositions, including platform basin of marine facies, foreland basin of marine facies, hollow—rented basin of relic sea,depression basin of continental facies, vibration basin of continental facies and contraction basin of continental facies. During hollow renting and depression, hydrocarbon source rocks were mainly developed. THis paper probed into the distribution and thermal evolution of hydrocarbon source rock, and presented the characteristics of structures and deposi—tions in hinderland of Junggar basin. Three favorable hydrocarbon—bearing areas were pointed out in this paper.
